Summary
What this review covers
This review looks at the listed four-inch fan size, ten speed levels, oscillation, IP-54 housing, product image, and fit for propagation shelf airflow.
Pros
The upside
- The four-inch fan head suits narrow seed-starting shelves and compact propagation corners.
- Ten speed levels give the airflow a careful adjustment range for daily plant checks.
- The clip mount keeps table space open around trays, labels, and watering tools.
Cons
The tradeoffs
- The fan still needs a dry cord route near trays, domes, and misting bottles.
- Very young sprouts need a gentle angle and distance during early airflow rounds.
Who it is for
Fit and feel
Good match:
This fan fits seed-starting shelves, small greenhouse benches, grow tents, and propagation corners where a clipped fan can stay near trays without taking over the work surface.
What to know:
Airflow should feel gentle around young starts. Begin with a soft setting, watch leaf movement, and adjust the angle as the plants grow.

Breakdown
Full review
A small fan for active seedling shelves
The AC Infinity CLOUDRAY S4 is a four-inch clip fan made for small grow spaces. It brings moving air to a shelf, bench, or covered plant corner where trays, domes, lights, and watering tools already share the space.
The smaller fan head helps the fan sit near a propagation area with careful placement. Clip it to a shelf upright, frame, or bench edge where the airflow can move across the plant zone with a gentle side angle.
Speed and oscillation control
The ten speed levels give the airflow room to start softly. That matters on seed-starting shelves because young plants change quickly from covered germination to leaf growth.
Oscillation helps the moving air travel across the shelf. A light sweep can support a fresh-feeling plant area during long days under lights.
Placement habits
Keep the cord path dry and visible. Propagation areas often hold damp trays, mister bottles, capillary mats, and dome covers, so power routing deserves a clear place before the fan runs.
Use the fan as part of the daily tray round. Check the soil surface, dome vent, monitor reading, and fan angle together. That routine keeps airflow tied to what the seedlings are doing.
